We have consistently adhered to the concept of high-quality services and own an agile, efficient, experienced and energetic team. We regard product quality as our own lives and see products as our characteristics. We conduct this management concept thoroughly and try to promote the core competitiveness of our products through continuous R&D and innovation.
ODMT introduces foreign advanced technology and carefully improves the products according to their actual application in China. The key components are imported products. We have a perennial partnership with Germany FESTO, Germany EFM, France Schneider, Italy ASTON, etc. These world-renowned companies have been providing high-quality accessories for ODMT, so we have a guarantee in our product quality. The mechanical parts like the body are localized, so they have the quality of imported products and the price of domestic products, favored by machinery manufacturers.
ODMT focuses on the training and developing of professionals. We have a highly qualified professional team. Product development, mechanical design, equipment testing and technical services are all conducted by professional and technical personnel. We have established a complete after-sale service system so that customers can erase their worries after purchasing the products. Users can feel assured to buy and at ease to use our products.
Working Process of Pneumo-hydraulic Drives
The initial state: Air inflows through P1 inlet. The working piston is in initial position;
The speeding stroke: Air inflows through P2 inlet. The working piston moves to workpiece rapidly under the effect of compressed air. This process only includes pneumatic movement, so it has the aerodynamic characteristics of small force and fast speed. This can realize the purpose of soft contact with the workpiece, thus protecting the molds and workpiece;
The force-amplifying stroke: After the working piston contacts the workpiece, the pneumatic pressure in P2 outlet increases. Open the special valve D and the power piston begins to move. According to the principle of force balance, hydraulic pressure in the working oil cavity will increase. The high-pressure oil drives the piston rod, thus realizing large pressing force output;
The return stroke: After finishing the pressing process, air inflows through P1. The working piston returns rapidly under the effect of the pneumatic pressure. At the same time, the power piston returns rapidly under the effect of the spring.
The pneumo-hydraulic drive produced by our company is a complete power component. Its different structures meet different needs. It can also be designed according to requirements.
The perfect sealing unit increases its lifespan uttermost.
1.With a positioning convex flange plate, the pneumo-hydraulic cylinder can be installed on the body accurately.
2.Both sides of the working piston are installed with durable buffers, to ensure low noise in high-speed working process.
3.The sealing elements are specially lubricated before installation. Air without lubrication is allowed.
4.After a long-term test and adjustment, all the seal installation technology is optimized.
5.Complete air-oil separation, succeed in preventing air into the oil chamber and ensure the pneumo-hydraulic drives have long working lifespan.
6.Double-supported piston rod ensures the pistons precision.
7.Each pneumo-hydraulic cylinder has a high pressure measurement and control interface, which has the following functions
setting pressure which is not affected by compressed air pressure, to control the return stroke.
monitoring systems pressure and controlling pressing quality.
the following functions can be introduced, such as connecting the welding current after reaching the set pressure.
connected with pressure gauge, etc.
Oil can be filled into the cylinder through the pressure testing interface.
8.Constant pressure oil storage system, storing enough hydraulic oil for the cylinder to work.
9.Preloading piston provides constant pressure for oil storage system.
*0.The spring has double functions. It can make the power piston return to its initial position and preload the oil storage chamber. So when the gas path of the cylinder is closed, the oil storage chamber can also guarantee a certain amount of preloading, thus ensuring its working condition in any installation directions and positions. Besides, the spring can also reduce air consumption while working. The piston returns to its initial position non-pneumatically. Compressed air is not needed.
*1.The requirement of non-force stroke can be realized by changing the force-amplifying piston.
*2.Whenever working piston meets resistance, force-amplifying stroke switch will open automatically. The working process turns into force-amplifying stroke and controlled by throttle X.
*3.Force-amplifying stroke switch valve has been installed on the cylinder. The pneumo-hydraulic cylinder has double modes of action.
Technological Advantages of Equipment with ODMT-powerpackage
Compared with the traditional ways to drive the press equipment, the press equipment withODMT-powerpackage has advanced performance and it is economic and reliable. This is because we have installed the ODMT-powerpackage, which are produced by our company by introducing advanced technology abroad, into all of our pressing equipment.
●Maximum 8Kg compressed air drive, can produce ****0 tons of pressure without hydraulic system. Pressing force can be adjusted within the rated maximum.
●Completely new pressing equipment with three strokes Purely pneumatic speeding strokeidle stroke drives molds to contact workpiece rapidly and softly, without impact; force-amplifying strokeafter contacting the workpiece, the process turns into the this stroke automatically; return strokeafter finishing stamping process, the pneumatic force returns rapidly.
●The most advanced technology of soft contact In idle stroke, the pressing molds are driven by low-pressure compressed air, contacting the workpiece rapidly and softly without impact nor noise. This can improve the pressing quality, the lifespan of the molds, and the environment of pressing process.
●Unique technology of amplifying force automatically Within the strokes, wherever it is, as long as the mold touches the workpiece, the cylinder will turn from the speeding stroke to the force-amplifying stroke automatically, then conducts the stamping process. There isnt any additional adjustment control. There is no need to adjust the strokes when replacing different workpieces or molds.
●Linear pressure distribution The air pressure and the output air pressure distribute linearly within the whole strokes. This feature makes ODMT—powerpackage the most ideal press equipment.
●Intelligent control Pneumatic control, simple and reliable, easy to operate and maintain. Computers monitor the process intelligently through programming, thus realizing automization in the whole pressing process.
●High reliability The cylinder is highly integrated. It has only three moving parts and the seal structure which has been tested over and over again. It has high efficiency, long life span and no leakage.
●Extremely low energy consumption and high working efficiency Compared with the air cylinder, oil cylinder and the traditional crank slider type pressing machine, its highest energy saving can reach *0%. This is because our pneumo-hydraulic cylinder only works in full power during the force-amplifying stroke. In speeding stroke and return stroke it is driven pneumatically during which it consumes a little bit energy. Some types of the equipment can reach a maximum working efficiency of **5 times per minute.
The press equipment produced by our company is more economic in the molding industry. We can design and produce multi-position machines and fully automatic production line according to your special requirements on space size, equipment function, control system, etc.
